Linear equations involve variables raised to the power of 1, represented by straight lines on graphs.
When solving a linear equation, if both sides of the equation result in contradictory statements, such as 3 = 5, there is no solution.
A linear equation has one solution when both sides of the equation are equal, resulting in a single value for the variable, e.g., 2x + 3 = 7.
Infinite solutions occur when both sides of the equation are identical, meaning every value for the variable satisfies the equation, e.g., 3x - 4 = 3(x - 1).
Provide examples of linear equations for students to solve, reinforcing the concepts of no solution, one solution, and infinite solutions.
